Message-ID: <1491211273-10910-2-git-send-email-Yuval.Mintz@cavium.com>
Date: Mon, 3 Apr 2017 12:21:09 +0300

Subject: [PATCH net-next 1/5] qed: Revise QM cofiguration
From: Ariel Elior <Ariel.Elior@...ium.com>
Refactor and clean up the queue manager initialization logic.
Also, this adds support for RoC low latency queues, which later
would be used for improving RoCE latency in high throughput scenarios.
